 # Installation
 
-## Linux (Dexoron Packages)
+## dcrup (recommended)
 
-Configure your package manager at https://pkg.dexoron.su and install:
+Install and switch DCR versions (stable / dev / night, pin `0.8.2`, optional build from source).
 
-**Arch Linux**
+### Linux / macOS / BSD / Windows (bash)
 
 ```sh
-sudo pacman -Sy dcr
+curl -fsSL https://sh.dcr-tool.ru | sh -s -- self-install
+export PATH="$HOME/.dcr/bin:$PATH"
+dcrup install stable
 ```
 
-**Debian/Ubuntu**
+Non-interactive install of DCR in one shot:
 
 ```sh
-sudo apt update && sudo apt install dcr
+curl -fsSL https://sh.dcr-tool.ru | sh -s -- install stable
+export PATH="$HOME/.dcr/bin:$PATH"
 ```
 
-**Fedora/RHEL**
+### Windows (PowerShell)
+
+```powershell
+irm https://ps1.dcr-tool.ru | iex
+# or download then run:
+# irm https://ps1.dcr-tool.ru -OutFile dcrup.ps1
+# powershell -File .\dcrup.ps1 self-install
+# $env:Path += ";$env:USERPROFILE\.dcr\bin"
+dcrup install stable
+```
+
+Optional cmd bootstrap (if you prefer `curl` of the cmd shim):
+
+```bat
+curl -fsSL -o dcrup.cmd https://cmd.dcr-tool.ru
+```
+
+After `self-install`, the command is **`dcrup`** (no `.sh` / `.ps1`): shims live in `~/.dcr/bin` (Unix) or `%USERPROFILE%\.dcr\bin` (Windows `dcrup.cmd`).
+
+### Common dcrup commands
 
 ```sh
-sudo dnf install dcr
+dcrup install stable              # latest stable prebuilt
+dcrup install 0.8.2               # pin → 0.8.2@stable
+dcrup install 0.8.2@dev
+dcrup install stable --libc musl  # Linux: musl asset (default: gnu)
+dcrup install stable --build      # cargo build --features archive
+dcrup install night               # always build from branch dev HEAD
